Sweden has commissioned Rheinmetall to supply eight Seasnake 30 weapon systems for the Swedish Navy.

The Seasnake 30 is a remote-controlled naval light gun designed for close-range defence. Alongside the weapon itself, the system incorporates modern daylight cameras, infrared sensors, and a laser rangefinder.

It features automatic target detection and the ability to track multiple targets simultaneously. The revolver cannon’s nominal maximum rate of fire is 1,100 rounds per minute.

These systems will be the primary armament of the new Combat Boat 90 fast military assault craft. The first order under the framework agreement is worth around €63 million and was placed in February 2026.

The framework agreement also includes airburst and 30 mm calibre training ammunition, with a term of four years. Spare parts and services are also included in the agreement. Additionally, the contract includes an option for up to 29 extra Seasnake weapon systems.

According to Rheinmetall, thanks to its integrated airburst capability, the Seasnake 30 is particularly effective against air targets, such as drones. Its low silhouette and compact stealth design also make it difficult for enemy sensors to detect.

Delivery of the first system is scheduled for February 2028.

Combat Boat 90 is a fast military assault craft developed by Swedish boat maker Dockstavarvet, a part of Saab. Commissioned in 1991, the unit can function as a fast assault and coastal defence boat, a patrol boat, or a special operations support vessel. It can also be used for reconnaissance, surveillance and intelligence-gathering operations.
